1.【计】预处理程序
1.a piece of software that partly prepares information before it is used
1.That is, a variable name should not be passed to a preprocessor directive and a symbol can only be evaluated by a preprocessor directive.
即，不应将变量名传递到预处理器指令，并且只能用预处理器指令计算符号。
2.and a compiler is, in some sense, just a very fancy preprocessor.
从某种意义上讲，编译器就是一个非常奇妙的预处理器。
3.The preprocessor can extract clock information from NRZ data stream, which consists of a delay cell, a multiplier and a narrow-band filter.
预处理器主要有延迟单元、乘法器和窄带滤波电路构成，可以从NRZ数据中得到时钟信号。
4.Xcode needs to be configured to tell the preprocessor to search this directory when processing #include directives.
需要通过配置Xcode让预处理器在处理#include指令时搜索这个目录。
5.A preprocessor token can be a header name, identifier, number, character literal, string literal, symbol, or miscellaneous character.
一个预处理记号可以是头文件名、标识符、数字、字符类型、字符串类型、元素或者混合字符。
6.The C preprocessor allows only a fixed number of arguments to its macros.
C预处理器对于自己的宏只允许使用有限数目的参数。
7.Hypertext Preprocessor (PHP) is cross-platform scripting language used to compose dynamic Web pages and server-side application software.
超文本预处理器（PHP）是一种跨平台的脚本语言，用于编写动态网页和服务器端应用程序软件。
8.A preprocessor directive must be the only instruction on a line.
预处理器指令必须是行上的唯一指令。
9.As a result, the specialized preprocessor is at least 10 times faster than any solution with XML parsing.
所以，这个专业的预处理器比其他任何的XML解析方案都要快至少10倍。
10.The -a option, requiring no argument, instructs NASM to replace its powerful preprocessor with a stub preprocessor which does nothing.
a选项不要求任何参数，通知NASM的强大的预处理器不进行任何处理。
